I want to get some usdt on either of these networks. Reason is because I want to send a few tiny payments. By tiny payments... i mean like 5 dollars and under and thus sending usdt via ETH makes no sense due to the fees.
I have access to coinbase and gemini.
You are going to open another account in another exchange like FTX, Kucoin or Binance which support USDT TRC20 or USDT BEP20
Does this mean if I get usdt in the BSC Bep 20 network... I need that coin to pay my fee? What coin would that be?
Yes, you will need some BNB BEP20 to pay for the gas fees
Also what has me confused is say I get usdt in Tron network. When you want to send usdt in tron network to someone... do you need to make two separate transactions? One is sending the Tron fee first... and then send the usdt in the tron network? Do you make each payment one after another to the usdt tron address you are sending to?
No, the tron act as gas fee from the sending address. There is no need to send it to the receiving address unless if you want to help the fund their next transaction fee.
Would I just get btc and then use one of those anonymous crypto services like changelly to do this? Or fees are very high if I'm doing a small amount?
Services like changelly are useless for such small amounts.
